Description

[Detailed explanation of the invention] "Industrial application field" This invention checks the material of the coins one by one, counts the number of coins, and sequentially inserts them into a stacking cylinder until a predetermined number of coins have been accumulated. The present invention relates to an improvement of a coin counting and packaging machine that sends the accumulated coins to a packaging section and wraps and tightens wrapping paper.

``Prior art'' Coin counting and packaging machines are usually designed to count and package sorted coins of the same denomination.
Therefore, if a different type of coin is exceptionally mixed into these coins, it is necessary to remove the different type of coin, and even if the sorted coins are fed into the coin accumulation cylinder, it is necessary to remove the different type of coin. However, if the coins are arranged in an irregular manner, it is necessary to detect and correct this.

As a coin wrapping machine having the latter function, the technique disclosed in Japanese Patent Application Laid-Open No. 127892/1982 has been known (a coin wrapping machine having the former function will be described later).

This coin wrapping machine with an irregularity detection function is equipped with a through hole formed on the side surface of the stacking tube, a light projector that emits light that passes through the through hole, and a light receiver that receives the light projected from the projector. If the light emitted from the projector is not detected by the receiver even though a certain number of coins are not stored, it is assumed that the coins are misaligned in the stacking tube. .

By the way, in such an abnormality detection device using optical means, depending on the irregularity of the coins, light may leak from the gaps between the coins and cause false detection. Despite this, there were problems when the coins were packaged.

As a coin wrapping machine capable of solving such problems, a technique disclosed in Japanese Patent Application Laid-open No. 74188/1983 is known.

The irregularity detection device for a coin packaging machine disclosed in Japanese Patent Application Laid-Open No. 54-74188 has an electrode that contacts the top of the coins stored in a stacking cylinder, and detects abnormalities in the accumulated coins depending on the contact height position. and detects whether or not coins have been accumulated in the accumulating tube by establishing electrical continuity between the electrode and a pin provided on the bottom plate of the accumulating tube via the accumulated coins. It is.

However, in such a misalignment detection device, even if different types of coins are mixed in the stacking tube, if the coins are correctly accumulated in a layer in the stacking tube, the electrode and the pin will be in a conductive state. On the other hand, there was a problem in that these accumulated coins were sent to the next packaging process.

Furthermore, as mentioned above, JP-A-54-74188
Utility Model Application Publication No. 57-137065 was developed as a technology that has a function to eliminate defects in the misalignment detection device shown in the publication.
BACKGROUND OF THE INVENTION A dissimilar coin detection device for a coin counting and packaging machine as shown in the above publication has been known.

The different type coin detection device of this coin counting and packaging machine includes a conveyor belt that is installed along a coin movement path, whose belt surface contacts the top surface of the coin, and conveys the contacting coins toward a stacking cylinder; The coin is equipped with a magnetic sensor (detection coil) provided on the conveyance path of the coin, and a stopper provided behind the magnetic sensor and removably in the movement path of the coin to restrict movement of the coin. By detecting changes in the magnetic flux generated by the magnetic sensor, both the denominations are confirmed and counted, and when the magnetic sensor detects that different types of coins are mixed in, the stopper is activated. It is out against the movement path of the coin,
This restricts the conveyance of coins to the stacking tube.

``Problems that the invention attempts to solve'' However, since different types of coins are detected in the different type coin detection device of such a coin counting and packaging machine, problems such as those shown in Japanese Patent Application Laid-open No. 74188/1988 occur. However, on the other hand, problems occurred as shown below. In other words, (1) Since the magnetic sensor and the counting stopper are provided along the coin transport direction, the magnetic sensor detects an abnormality in the coin and the counting stopper is moved out of the coin movement path. In some cases, the protruding counting stopper may cause abnormal coins to be thrown back, causing the magnetic sensor to count the abnormal coins again, resulting in a miscount.

(2) Since magnetic sensors are used to count and check the material, if non-metallic imitation coins, such as toy coins made of plastic or hard paper, are mixed in. However, there was a problem in that the magnetic sensor supplied the imitation coins to the stacking tube without showing any reaction, and the stacked coins were packaged.

``Means for solving the problem'' This idea was made in view of the above circumstances, and was designed to prevent miscounts caused by the magnetic sensor, and to prevent excess or deficiency of coins of the same denomination in the stacking tube. The purpose of the present invention is to provide a coin packaging machine that can accommodate coins without any problems, and in order to achieve this purpose, a magnetic sensor is provided in a sorting passage for sorting coins to count the number of coins and check the material; provided at a position facing the magnetic sensor across the sorting passage,
Based on the abnormality detected by the magnetic sensor, the stacked coins introduced into the stacking cylinder after passing through the counting stopper that restricts the movement of the coins and the sorting passage are clamped by the upper and lower clamping members, and the coins are separated. An irregularity detection device that tests for irregularities depending on the stacking height; and a continuity detection device that electrically tests for the presence of non-metallic imitation coins using lead wires connected to the two clamping members of the irregularity detection device. and a control means for starting the packaging process only when no irregularities occur and continuity is found through inspection of the irregularity detection device and the continuity detection device.

"Operation" According to this invention, since a magnetic sensor and a counting stopper are provided in the sorting passage, an abnormality in the coin is detected by the magnetic sensor, and the coin is moved by the counting stopper based on the detection result of the magnetic sensor. is regulated. Furthermore, since the magnetic sensor and the counting stopper are provided at positions facing each other across the sorting path, when the counting stopper operates, the movement of abnormal coins detected by the magnetic sensor is restricted by the counting stopper. Placed past the position. This prevents abnormal coins from being bounced back by the counting stopper.

On the other hand, the misalignment detection device detects misalignment of the coins in the stacking cylinder, and the continuity detection device detects continuity of the coins.

By conducting a continuity test on such accumulated coins, it is possible to detect, for example, plastic,
It is detected that a non-metallic pseudo coin made of hard paper or the like is mixed in.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view of essential parts of an embodiment. This coin counting and packaging machine runs coins 2 on a sorting path 1 on a conveyor belt 4 driven by a pulley 3, sequentially inserts them into a stacking cylinder 5, and collects a predetermined number of hard coins (usually 50 coins). This type forms a stack of coins and transfers the stacked coins to a predetermined position (packaging section) below for packaging.
There is a shutter plate 6 that closes the lower part of the stacking cylinder 5 and supports the coins 2 in the cylinder until the coins are loaded, and a shutter plate 6 that closes the lower part of the stacking cylinder 5 and supports the coins 2 in the cylinder. Instead, a support rod 7 is arranged to support the accumulated coins.

The sorting passage 1 includes a fixed sorting shelf 1a fixed to the frame side of the packaging machine, and a movable sorting shelf 1b linked to a denomination dial 8 for setting the denomination of coins to be packaged.
By operating the denomination dial 8, the passage width can be adjusted to match the coin diameter. A magnetic sensor 9 is provided on the movable sorting shelf 1b side and a counting stopper 10 is provided on the fixed sorting shelf 1a side in the sorting passage 1 near the stacking cylinder 5. The magnetic sensor 9 and the counting stopper 10 are arranged at positions facing each other in the width direction of the passage so as to be at the same position with respect to the coin conveyance direction.

The magnetic sensor 9 allows a magnetic flux of a predetermined strength to cross the coins passing through the passage, and detects the magnetic flux changed by the hard material 2, thereby confirming the location of the coins 2 and counting them. , is connected to a comparison circuit that memorizes the detection level according to the material of each denomination in advance and compares it with the actually detected magnetic flux, so that the denomination can be discriminated at the same time as counting, so that the counted value is equal to the predetermined number. When a foreign coin is detected or a different type of coin is detected, the counting stopper 10 is operated to stop the supply of coins.

The counting stopper 10 has a semicircular cam portion 10b formed by notching one side of a cylindrical shaft 10a that passes through the fixed sorting shelf 1a, and rotates the shaft 10a so that the cam portion 10b is connected to the passage 1. The running of the coin 2 is stopped by making it protrude inward. The rotation of the shaft 10a is performed by a rotary solenoid (not shown) operated by a signal from the magnetic sensor 9 described above or a signal from a control device described later.

When the count value by the magnetic sensor 9 reaches a predetermined number and the supply of coins 2 is stopped, the irregularity detection device 11
This detects the irregularity of the stacked coins stacked in the stacking tube 5, and the continuity detection device detects the presence or absence of electrical continuity of the stacked coins.

The irregularity detection device 11 is for holding the stacked coins in the stacking tube 5 between the shutter plate 6 and a detection rod 13 arranged above the stacking tube 5, and is positioned by the denomination dial 8. Reed switch 14 and arm 1 supporting the detection rod 13
The misalignment is detected based on the relative position of the actuating piece (magnet) 16 which is attached to the reed switch 5 and operates the reed switch 14.

The reed switch 14 is attached to a grooved sleeve 18 that is movably supported by a guide shaft 17 in the direction in which coins are piled up (vertical direction).
The height position is adjusted via a lever 19 whose tip 19a is engaged with a groove 18a of the grooved sleeve 18. The lever 19 has a base end 19b
is pivotally supported by the frame and is movable in the vertical direction, and a roller 19c is provided at the intermediate portion thereof.
is in contact with a denomination cam 20 integrated with the denomination dial 8, and adjusts the height of the reed switch 14 in accordance with the coin set by the denomination dial 8.

The arm 15 is supported by a guide shaft 21 so as to be movable in the same direction as the grooved sleeve 18, and is urged vertically downward by a spring 22, and is connected to a solenoid 24 via an arm operating lever 23. receives a vertically upward force from The arm operating lever 23 has a bearing portion 23 at its intermediate portion.
A is pivotally supported by the frame and is freely rotatable in the vertical direction. Further, the solenoid 24 is energized while the coins continue to be inserted into the collecting cylinder 5, and the arm 1 is energized.
5 is pushed upward, and when the magnetic sensor 9 finishes counting and the coin insertion operation is completed, the excitation is released. When the arm 15 is lowered by the biasing force of the spring 22 and the tip of the detection rod 15 comes into contact with the upper end of the accumulated coins, the actuating piece 16
If the heights of the reed switch 14 and the reed switch 14 match, the reed switch 14 is turned on, and the control device connected to the reed switch 14 detects that it is normal, and the operating piece 16 and the reed switch 14 are connected to each other. 14, the reed switch 14 is turned off, and the control device detects that the heights are not aligned.

The shutter plate 6 and the detection rod 13 are both made of metal, and the detection rod 13 is connected to the arm 15 by an appropriate means such as an insulating bush.
insulated from Lead wires 25a and 25b are electrically connected to the upper ends of the shutter plate 6 and the detection rod 13, respectively. These lead wires 25a and 25b are each electrically connected to a continuity detection device, and when detecting irregularities in the stacked coins, electrically contact the end face of the stacked coins via the detection rod 13 and the shutter plate 6, and The presence or absence of conduction of the accumulated coins is detected by this. If there is continuity, it is normal; if there is no continuity, it means that non-metallic imitation coins are mixed in the accumulated coins. Such detection results are sent to a control device to which the reed switch 14 is connected. In this control device, reed switch 14 is ON.
Then, only if there is continuity at the same time, the accumulated coins are judged to be normal and processed to move on to the next packaging operation.In cases other than the above, the accumulated coins are judged to be abnormal. Appropriate processing such as removing the accumulated coins to a reject box or displaying them with an alarm etc. is performed. The abnormal situation is displayed by the alarm or the like, and the presence or absence of continuity and the presence or absence of irregularity are individually displayed, so that the abnormal situation can be clearly read.

As described above, the lead wires 25a and 25b connected to the continuity detection device are attached to the two members (in this embodiment, the detection rod 13 and the shutter plate 6) that sandwich the stacked coins of the irregularity detection device 11, and these two members are connected to each other. If the lead wires 25a, 25b are brought into contact with the upper and lower ends of the stacked coins by the irregularity detection operation of the members 6, 13, the presence or absence of conduction of the stacked coins will be detected at the same time as the irregularity is detected, and in particular, the detection time will be increased. It is possible to detect the presence of non-metallic imitation coins even without providing a counter. Further, since the lead wires 25a, 25b are brought into contact with and removed from the accumulated coins automatically by the irregularity detection device 11, a dedicated drive mechanism is provided for bringing the lead wires 25a, 25b into contact with the accumulated coins. It is not necessary to use the present invention, and it can be easily applied to conventional packaging machines, and the cost increase and the complexity of the detection device are reduced.

3 and 4 show other embodiments of this invention.

The coin counting and packaging machine in this embodiment holds the stacked coins C formed in the stacking barrel 5 between clamping rods 26a and 26b disposed above and below the stacking barrel 5, and moves the coins C from the stacking barrel 5 in a horizontal direction (lateral direction). This type of packaging is carried out by being transferred to a packaging section 27 located far away. In this type of packaging machine, the clamping rod 26a
and 26b correspond to the detection rod 13 and shutter plate 6 in FIG. 1, respectively, and form a part of the misalignment detection device 11. These clamping rods 2
6a and 26b are both made of metal material, and lead wires 25a and 25b connected to the continuity detection device are attached to these clamping rods 26a and 26b, as in the previous embodiment. .

Supplementary explanation regarding FIGS. 3 and 4 is that 27a is a fixed roller for packaging, 27b is a movable roller, and 28 is a clamping bar 26a and the clamping bar 26a.
This is a bush that insulates the connecting part with the arm 15 that supports the arm 15. Other components that function in the same manner as in the previous embodiment are given the same numbers to simplify the explanation. Further, in these figures, broken lines and two-dot chain lines indicate the positions to which each component moves.

In the coin counting and packaging machine configured as described above, a counting stopper 10 and a magnetic sensor 9 are provided in the sorting passage 1, and a pair of lead wires 25a, 25 connected to the continuity detection device are connected to the irregularity detection device 11, respectively. Since the structure is such that the lead wires 25a and 25b are attached to two members that sandwich the accumulated coins, and both lead wires 25a and 25b are brought into contact with the upper and lower ends of the accumulated coins by the misalignment detection operation of these two members, the output of the magnetic sensor 9 can be used. The configuration and counting control of the sorting passage 1 are simplified by counting the number of coins and checking the material, and the presence or absence of conductivity of the accumulated coins is simultaneously detected when the irregularity detection device detects an irregularity, and in particular, a new detection time is provided. At the very least, it is possible to know if non-metallic imitation coins are mixed in, thereby preventing the inconvenience of packaging a stack of coins mixed with imitation coins. Further, contact and detachment of the lead wires 25a and 25b from the stacked coins can be prevented by the irregularity detection device 1.
1 automatically, the lead wire 25
There is no need for a dedicated drive mechanism for bringing a and 25b into contact with the accumulated coins, making it possible to provide a compact coin detection function at low cost. Further, since the magnetic sensor 9 and the counting stopper 10 are provided at positions facing each other across the sorting path 1, when the counting stopper 10 operates, the abnormal coins detected by the magnetic sensor 9 are transferred to the counting stopper 10. It is placed passing through a position where movement is restricted by.

This prevents abnormal coins from being bounced back by the counting stopper 10, thereby preventing erroneous counting and improving work efficiency.

"Effects of the invention" As explained in detail above, according to this invention, the magnetic sensor and the counting stopper are provided at positions facing each other across the sorting passage.
When the counting stopper operates, the abnormal coin detected by the magnetic sensor passes through a position where movement is restricted by the counting stopper and is placed. This prevents abnormal coins from being bounced back by the counting stopper, thereby preventing erroneous counting and improving work efficiency.

On the other hand, since a misalignment detection device and a continuity detection device are provided to check for misalignment of coins in the stacking cylinder and to check continuity of coins, the coins are stored in the stacking cylinder without excess or deficiency. In addition, it is possible to detect the presence of non-metallic pseudo-coins made of plastic, hard paper, etc. in the collected coins, and to ensure that coins of the same denomination are packaged. be effective.
